Introduction

The launcher icon for your app (sometimes called an "app icon") is the icon that a user taps to start your app. For commonality with Android, starting in Fire OS 5, Amazon uses icons from your APK. (This is a change from earlier versions of Fire OS, where the launcher used the launcher icon that you uploaded to the developer portal when submitting your app.)

As you create your launcher icons, be aware of the following guidelines and troubleshooting. Note that the following sections apply to Fire OS 5 and Fire OS 6.

Scaling

The launcher avoids scaling launcher icons, unless absolutely necessary. To display large and crisp icons on a device, the launcher fetches the icon with a density higher than that of the device.

Icon size and densities

Create a version of your icon at each of the following dimensions and include the images in your APK. Make sure that your icons are in the appropriate res folders so that the launcher can find them:

Generalized density

Icon dimensions

Res folder

Requested by

xxhdpi

144px x 144px

drawable-xxhdpi

xhdpi Amazon devices

xhdpi

96px x 96px

drawable-xhdpi

tvdpi, hdpi Amazon devices

hdpi

72px x 72px

drawable-hdpi

mdpi Amazon devices

Icon File Format

Provide the images for your launcher icons in 24-bit PNG format.

Troubleshooting Your Launcher Icon

If your launcher icon is not displaying as expected, consider the following:

Problem: The wrong icon is displayed or the icon is scaled up or down and looks bad.

Solution: If you provide the launcher icon for a configuration such as drawable-large-mdpi, Android resource-resolution rules might select the icon from that folder instead of the appropriate folder.

See the Android documentation here
for the Android resource resolution algorithm.

To help ensure that the launcher selects the correct icon, only include icons in the resource folders listed in the table on this page.

Solution: Some tools build an APK for a specific density and remove other drawables. For example, the tools might remove the drawable-xxhdpi folder, even though Amazon uses the xxhdpi icon file on xhdpi devices. To help avoid this issue, use a mipmap-* pattern for folder names instead of drawable-*:

mipmap-hdpi: 72px

mipmap-xhdpi: 96px

mipmap-xxhdpi: 144px
